涎腺肌上皮瘤临床分析

目的探讨涎腺肌上皮瘤(myoepithelioma,ME)的临床特点、发病情况及其手术治疗方法.方法对1999～2004年收治的10例患者进行回顾性分析.结果ME好发于腮腺及腭部,且发生于腭部的比例较多形性腺瘤明显上升.ME的临床表现与多形性腺瘤相似,主要依靠病理诊断.对腮腺来源的ME实施保留面神经的腮腺全切术,效果良好;对发生于腭部的ME实施局部扩大切除,仍有部分复发.结论ME是一种并非十分罕见的肿瘤,临床表现无特异性,部分肿瘤尤其是发生于腭部者,具有侵袭性生长或潜在恶性的特点,应适当扩大切除范围.

Clinical analysis of salivary myoepithelloma

Objective: To study the clinical features and operation method of salivary myoepithelioma.Method: 10 patients were reviewed with ME from 1999 to 2004 after 1-month to 5-year follow-up. Results: ME occurred mostly in the parotid gland and minor salivary gland of the palate. The proportion of ME in the palate rised considerably in camparison with mixed tumor. ME had similar clinical features with mixed tumor.In the ME of parotid gland, parotidectomy with retaining facial nerve can expect a good therapeutical result.While in the palate salivary ME, radical resection was not enough to prevent the recurrence completely. Conclusion: ME is not a kind of rare tumor and doesn't have particular clinical features.Part of the ME, especially in the palate,suggests aggressive or malignant potential.Properly enlarging the resectable bounds of tumor is recommended.
